Understanding robots.txt

What Is a robots.txt File?

A plain text file placed at the root of your website that tells search engine crawlers which pages or files they may or may not request.

A Guide for Crawlers, Not a Firewall

robots.txt uses directives like User-agent, Allow, Disallow, and Sitemap to give instructions to crawlers. It is a request, not an enforcement mechanism — malicious bots may ignore it entirely.

Why Use One?

It can help direct crawl budget toward important content, discourage crawling of admin areas or duplicate content, and point crawlers to your sitemap.

What It Cannot Do

It does not prevent pages from being indexed if other sites link to them. For true access control, use authentication or noindex meta tags.

Placement Matters

The file must live at the root of your domain (https://yourdomain.com/robots.txt) and be served with a 200 HTTP status. Subdirectory robots.txt files are ignored.

1. General Settings

Most major search engines ignore this. Useful for smaller bots.

2. General Allow / Disallow Rules

3. Bot-Specific Rules

4. Sitemap

Auto-generated from Website URL, or edit manually. If you need to create a sitemap, try our XML Sitemap Generator.

🤖

Bot-Specific Rules

Create custom User-agent blocks for Googlebot, Bingbot, or any other crawler, overriding the default rules.

📋

Pre-built Templates

Start from "Allow All", "Block All", or "WordPress Default" — one-click starting points for common setups.

🗺

Sitemap Integration

Adds the Sitemap: directive automatically from your website URL.

Copy or Download

Copy the content to clipboard or download as a ready-to-upload robots.txt file.

💾

Save Configurations

Store complex setups in your browser's local storage and reload them on future visits.

Honest by Design

This tool builds robots.txt directives. Here is exactly what it does and does not do:

  • ✓ Generates correctly formatted robots.txt directives from your inputs.
  • ✓ All generation happens in your browser — your configuration is not sent to our server.
  • ✓ Does not upload the file for you — you still upload it to your website's root directory yourself.
  • ✓ Does not guarantee search engines will follow your directives — compliant bots do, malicious bots may not.
  • ✓ Does not replace true access control — for private content, use authentication or noindex.

This tool does

  • Generate correctly formatted robots.txt directives
  • Support User-agent, Allow, Disallow, Crawl-delay, Sitemap
  • Create bot-specific rule blocks
  • Provide one-click templates
  • Run entirely in your browser
  • Save/load configurations from local storage

This tool does not

  • Upload the file to your server
  • Validate whether your directives are correct for your site
  • Force crawlers to obey the rules
  • Replace authentication for private content
  • Prevent indexing if other sites link to your URLs
  • Test whether your live robots.txt is reachable
Choosing the Right Method

robots.txt vs noindex vs Authentication

Three different tools for three different problems. Using the wrong one is the most common mistake.

Method
Controls crawling?
Controls indexing?
Protects private content?
robots.txt Disallow
Discourages compliant bots
Not if other sites link to it
Anyone with the URL can access
noindex meta tag
Page must be crawled to read the tag
Keeps URL out of search results
Anyone with the URL can access
Authentication (login)
Crawlers can't pass login
Not accessible to index
Real access control
HTTP 401 / 403 status
Server rejects the request
Not indexable
Real access control

The common mistake

Blocking a URL in robots.txt does not remove it from Google's index. If other sites link to that URL, Google can still show it in search results (without knowing what's on the page). To actually remove a page from search results, use noindex — but the page must be crawlable for Google to read that tag.

Quick Guide

How to Use This Generator

Four steps from configuration to uploading your file.

1

Set Defaults

Choose a template or set your default User-agent: * rules.

2

Add Custom Rules

Add specific rules for particular bots or disallow particular directories and file types.

3

Add Your Sitemap

Enter your website URL to auto-generate the sitemap directive, or enter the full sitemap URL manually.

4

Copy or Download

Copy the content or download robots.txt, then upload it to your website's root directory.

Troubleshooting Guide

Common Issues After Upload

If crawlers aren't behaving as expected after uploading robots.txt, check these common causes.

×

File Not Found (404)

UPLOAD ERROR

Crawlers cannot reach https://yourdomain.com/robots.txt.

Solution: Upload the file to the root directory of your website, not a subdirectory. Verify by visiting the URL in your browser.

!

Bots Still Crawling Blocked URLs

DIRECTIVE IGNORED

Some bots ignore robots.txt entirely, or other sites link to the blocked URLs.

Solution: Use noindex meta tags or password protection for truly private content. robots.txt is a request, not a block.

Pages Dropped from Index

OVER-BLOCKING

Too many Disallow rules may have blocked important content.

Solution: Review your rules. Use Google Search Console's robots.txt tester to verify you haven't blocked pages you want indexed.

Rules Not Taking Effect

CACHE DELAY

Search engines cache robots.txt and don't refresh immediately.

Solution: Wait 24–48 hours for crawlers to re-fetch the file. You can also request a refresh in Google Search Console.

Sitemap Not Detected

MISSING DIRECTIVE

Search engines haven't found your sitemap via robots.txt.

Solution: Ensure the Sitemap: line is present and the URL returns a 200 response. Also submit the sitemap directly in Search Console.

🔒

Private Content Indexed

WRONG APPROACH

You relied on robots.txt alone to protect private areas.

Solution: robots.txt does not secure content. Use authentication, HTTP status codes (401/403), or noindex for pages that must stay out of search results.

Decision Guide

Common Use Cases — What to Block and What to Allow

Use the generator for these common scenarios.

When you use it
What the robots.txt shows
What to do next
Block admin/private areas
Disallow: /admin/, /wp-admin/, /private/
Upload to root and verify in Google Search Console's robots.txt tester.
Prevent duplicate content crawling
Disallow URL parameters, print versions, or filtered views.
Combine with canonical tags to signal preferred URLs.
Protect server resources
Crawl-delay for aggressive bots, Disallow heavy file types.
Monitor server logs to confirm fewer requests from aggressive bots.
Point crawlers to your sitemap
Sitemap: https://yourdomain.com/sitemap.xml
Also submit the sitemap URL directly in Google Search Console and Bing Webmaster Tools.
Block specific aggressive bots
User-agent: AhrefsBot + Disallow: /
Also block by user-agent at the server level if the bot ignores robots.txt.
Control image indexing
User-agent: Googlebot-Image + specific Allow rules.
Monitor image search traffic to confirm the desired images appear.
Frequently Asked Questions

Robots.txt Generator FAQs

Answers based strictly on what this tool does and how robots.txt works.

?

Is a robots.txt file required?

No — a website works without one. But it can help guide crawler access and manage crawl behavior on larger or more complex websites, which is valuable for SEO.

?

What is the "Default User-agent"?

User-agent is the name of a crawler (Googlebot, Bingbot, etc.). The wildcard * means "all bots". Rules under the default user-agent apply to every crawler unless a more specific rule overrides them.

?

What is Crawl-delay?

A directive telling crawlers to wait a number of seconds between requests. Useful for slow or shared servers. Major search engines like Google ignore it, but many smaller bots respect it.

?

What do Allow and Disallow do?

Disallow tells a bot not to access a directory, file, or file type. Allow creates an exception — for example, blocking /images/ entirely but allowing /images/logo.png.

?

What are bot-specific rules?

Rules that apply only to a specific user-agent. They override the default * rules — for example, blocking /secret/ for all bots but allowing Googlebot to access it.

?

Can robots.txt prevent indexing?

No. It only discourages crawling. If other sites link to a blocked URL, search engines can still index it. For true removal from search results, use noindex meta tags or authentication.

?

Where do I upload the file?

At the root of your domain: https://yourdomain.com/robots.txt. Files in subdirectories are ignored. Verify by visiting the URL directly in your browser.

?

Is my configuration sent to your server?

No. All generation happens in your browser. Your configuration is never sent to our server. Only the downloaded file leaves your browser.
